Tongyi Full-Synthetic DHT Hybrid Transmission Fluid (DHTF)

Product Overview

Tongyi DHTF is a high-performance full-synthetic automatic transmission fluid independently developed for new energy hybrid vehicles equipped with DHT (Dedicated Hybrid Transmission). Formulated with premium full-synthetic base stocks and enhanced anti-wear additive packages, it perfectly adapts to the special operating conditions of dual-motor hybrid transmission systems. Featuring ultra-low electrical conductivity, excellent electrical material compatibility, outstanding high-temperature oxidation stability and anti-wear performance, this product solves the lubrication, insulation and wear-protection pain points of hybrid DHT gearboxes, effectively reducing component wear, avoiding electrical system interference, and extending the overall service life of hybrid transmission assemblies.

Core Technical Advantages

  • Low Conductivity & Electrical Insulation Protection: Adopts exclusive low-conductivity formula, effectively protects precision electronic components and motor parts inside DHT transmissions, avoids electrical corrosion and signal interference, and is fully compatible with new energy vehicle electrical materials.
  • Enhanced Dual-Motor Anti-Wear Technology: Optimized anti-wear additive system significantly improves extreme-pressure wear resistance, provides stable oil film protection for gears, bearings and clutch components under frequent start-stop and variable load conditions, and reduces mechanical wear.
  • Superior High-Temperature Stability: Premium full-synthetic base oil delivers excellent high-temperature oxidation resistance, suppresses oil deterioration, sludge and carbon deposition under long-term high-temperature and high-pressure operation, and maintains stable lubrication performance throughout the service cycle.
  • Smooth Shifting & Low Energy Loss: Precisely adjusted friction characteristics and excellent anti-foaming performance ensure smooth and stable shifting, reduce transmission power loss and heat generation, and improve overall transmission efficiency of hybrid vehicles.
  • Long Service Life & Durable Protection: Effectively resists electrochemical corrosion and mechanical fatigue damage, adapts to the frequent working conditions of hybrid DHT systems, and realizes long-cycle stable protection for transmission systems.

Wide Vehicle Compatibility

Specially designed for mainstream dual-motor and power-split hybrid DHT transmission systems in the market, fully compatible with major domestic and foreign hybrid models:
  • Chinese Brands: BYD DM-i, Geely Thunder DHT, GAC GMC, Great Wall Lemon DHT, SAIC EDU 1.0 / EDU 2.0, Chery Kunpeng DHT
  • Japanese Brands: Toyota THS Power-Split Hybrid System, Honda i-MMD Hybrid System

Typical Application Scenarios

Suitable for all new energy hybrid passenger cars equipped with dedicated DHT hybrid transmissions, covering urban daily commuting, high-speed driving and frequent start-stop working conditions. It is a special maintenance fluid for hybrid gearboxes, unavailable for traditional fuel vehicle automatic transmissions.

Packaging & Storage

Standard Package: 1L plastic bottle Shelf Life: 36 months (unopened, stored in cool and dry environment) Storage Conditions: Store indoors at 0°C ~ 40°C, avoid direct sunlight, high-temperature exposure and freezing. Keep containers tightly sealed to prevent moisture and dust contamination.

Important Notes

This product is dedicated to new energy DHT hybrid transmission systems. Do not mix with traditional ATF, CVT, DCT transmission fluids or engine oil. Select and replace the fluid strictly in accordance with the vehicle maintenance manual to ensure optimal transmission performance and service life.
